Different parts of J. adhatoda have been used for treatment of various ailments, mainly for the respiratory tract-based ailments. The present study was conducted to quantify the total antioxidant capacity (TAC), total phenolic content (TPC) and total flavonoid content (TFC) of different parts (mature leaves, immature leaves, flowers, bracts, soft stems, bark of mature stem and roots) of J. adhatoda using ferric reducing antioxidant power (FRAP) assay, modified Folin-Ciocalteu method and colorimetric method respectively. The results revealed that all tested parts of J. adhatoda contained marked amounts of TAC, TPC and TFC. Among tested parts, immature leaves showed a significantly higher TAC (19.28 ± 1.96 mg/TE g DW) followed by flowers (16.97 ± 0.99 mg/TE g DW) and bracts (14.19 ± 1.85 mg/TE g DW). Significantly the highest TPC (11.33 ± 0.14 mg/GAE g DW) and TFC (16.66 ± 3.06 mg/RE g DW) were observed in flowers followed by bracts and immature leaves. Moreover, there were positive correlations of TAC with TPC (R2 = 0.5411) and TFC (R2 = 0.5209). According to the results, it can be concluded that immature leaves, flowers and bracts of J. adhatoda contain marked amounts of bioactive compounds and hence could be effectively used for pharmaceutical industries.","PeriodicalId":23702,"journal":{"name":"World Journal of Agricultural Research","volume":"20 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87263313","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cultivation of ginger is mainly practiced by traditional farmers, and its commercialisation offers substantial income to farmers, traders and processors. The tuber contains enormous medicinal and nutritional potential, and can thus contribute to qualitative improvement of the diet of consumers. Despite the many advantages of this plant, it remained underexploited due to insufficient knowledge of cultivation methods, its cycle duration and its water requirement, which confines the crop mainly to the western region of Burkina Faso. Such under-exploitation has been exacerbated due to little attention dedicated to ginger research in the country. Therefore, preservation and improvement of ginger quality represent an important challenge for the various actors of this crop’s industry. The present review highlights the importance of ginger, its role in crop diversification, its medicinal and nutritional properties, as well as the future areas of selection and genetic improvement of this species in Burkina Faso.","PeriodicalId":23702,"journal":{"name":"World Journal of Agricultural Research","volume":"59 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78167970","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, varieties currently under cultivation are low yielding and susceptible to biotic or abiotic stresses. In such a context, an increase in sesame production would be possible either from an increase in the crop cultivation area or improvement of productivity traits. To create new and more productive varieties, seven lines from a local cultivar referred to as Senekuru were crossed with the improved and popular variety S42 during the dry season 2018-19, at Farakoba research station. Mid-parent heterosis, heterobeltiosis and the variability within the material were assessed during the rainy season 2019 using an Augmented Block Design. Standard agronomic practices were applied to the trials. The analysis of variance revealed highly significant differences among the genotypes for all the traits. Mid-parent heterosis and heterobeltiosis varied from cross to cross and from trait to trait. Concerning seed yield, the best value of mid-parent heterosis (87.44%) was obtained with Senekuru-3-1/S42, while Senekuru-2-1/S42 presented the best heterobeltiosis (40.34%). The main yield contributing traits in sesame production were plant height, branch number, and capsule number. Then, it was contended that hybrid seeds can significantly increase sesame productivity, provided that a practical hybridisation approach is applied.","PeriodicalId":23702,"journal":{"name":"World Journal of Agricultural Research","volume":"1 1","pages":"85-91"},"PeriodicalIF":0.0,"publicationDate":"2021-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84732397","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These practices directly influence the physical and chemical quality of the processed product. Therefore, the main objective of the present study was to analyze the effect of drying methods and packaging materials on total flavonoid content, total phenolic content, and total antioxidant capacity of five medicinal plant leaves with cosmetic potential. Leaves of Hibiscus rosa-sinensis L., Senna alata (L.) Roxb., Centella asiatica (L.) Urb., Ocimum tenuiflorum L. and Justicia adhatoda L. were dried to a constant weight using shade drier at 30-35°C, solar drier at 30-40°C and oven at 40°C. Thereafter, dried leaves were stored using three different packaging materials namely glass jars, polythene bags and gunny bags at ambient temperature for three months. Aluminum chloride colorimetric assay, folin-ciocalteau method, and phosphomolybdate assay were employed to analyze the total flavonoid content (TFC), total phenolic content (TPC) and total antioxidant capacity (TAC) of ethanolic extracts of leaves respectively in each month. Data were presented as mean ± standard deviation of minimum three replications. Significant interactions of the drying methods and packaging materials on TAC, TFC and TPC of dried leaf materials were analyzed using Two-way ANOVA. Results showed that the maximum TFC, TPC and TAC in oven dried H. rosa-sinensis (23.48±2.49 mg RE/100g DW, 1.09±0.24 mg GAE/100g DW and 0.39±0.05 mg AAE/100g DW respectively) and C. asiatica (128.64±10.59 mg RE/100g DW, 2.38±0.32 mg GAE/100g DW and 2.2±0.05 mg AAE/100g DW respectively) leaves stored in glass jars and solar dried S. alata (117.43±9.00 mg RE/100g DW, 3.99±0.29 mg GAE/100g DW and 1.07±0.04 mg AAE/100g DW respectively), O. tenuiflorum (216.02±0.75 mg RE/100g DW, 1.92±0.12 mg GAE/100g DW and 1.07±0.03 mg AAE/100g DW respectively) and J. adhatoda (11.13±1.23 mg RE/100g DW, 1.02±0.19 mg GAE/100g DW and 0.42±0.04 mg AAE/100g DW respectively) leaves stored in glass jars at the end of the storage period. However, statistically significant interaction (p value < 0.05) was not reported between drying method and packaging material on TPC of C. asiatica and O. tenuiflorum leaves and TFC of S. alata leaves. In conclusion, determining the effect of different processing methods on chemical constituents of aforementioned plant leaf materials is suggested to assure the quality of the final product.","PeriodicalId":23702,"journal":{"name":"World Journal of Agricultural Research","volume":"104 1","pages":"73-79"},"PeriodicalIF":0.0,"publicationDate":"2021-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90243837","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
